Perform common operations on strings such as changing case, truncating, finding/replacing, repeating, encoding/decoding, generating slugs, and more.
allowed="p|span|a" - pass "none" to strip all tags or a pipe (|) delimited list of allowed tags (default = allow all)
find="string1" - string to find (separate multiple values with the explode variable which defaults to "|", accepts regex)
replace="string2" - string to replace found string (default = "")
insensitive="yes" - toggle case sensitivity when finding a string (default = "no")
explode="|" - string to split find/replace parameters with
trim="left" - left, right, or both (default = "both")
encode="yes" - HTML encode the string (default = "no")
decode="yes" - HTML decode the string (default = "no")
url="yes" - URL encode the string (default = "no", set to "raw" for raw encoding)
capitalize="yes" - capitalize the first character of the string (default = "no")
title="yes" - capitalize the first character of every word (default = "no")
lower="yes" - convert the string to lower case (default = "no")
upper="yes" - convert the string to upper case (default = "no")
characters="10" - number of characters to truncate the string to (default = unlimited)
words="10" - number of words to truncate the string to (default = unlimited)
append="..." - if truncated append this to the end of the string (default = "…")
slug="yes" - convert the string to a slug (default = "no")
separator="_" - separator for slug (default = "-")
repeat="3" - number of times to repeat the string, great for prototyping (default = 0)
count="|" - return number of substring instances of a supplied string (default = false)
splits="|" - return number of exploded values from a supplied string (default = false)
typography="all|xhtml|br|lite" - Use ExpressionEngine's typography class
And here is more detailed information on the parameters available for the {exp:streeng} tag pair.
allowed="none"
or
allowed="p|span|a"
This will strip either all (if set to allowed="none") or the desired HTML tags from the string enclosed by the tag pair. If this parameter is not set the default is to allow all.
Example:
{exp:streeng allowed="none"}
<p>Our plans for <a href="http://youtu.be/GBkT19uH2RQ">world domination</a> are none of your concern. So go mind your own business!</p>
{/exp:streeng}
Result:
Our plans for world domination are none of your concern. So go mind your own business!
Example:
{exp:streeng allowed="a"}
<p>Our plans for <a href="http://youtu.be/GBkT19uH2RQ">world domination</a> are none of your concern. So go mind your own business!</p>
{/exp:streeng}
Result:
Our plans for <a href="http://youtu.be/GBkT19uH2RQ">world domination</a> are none of your concern. So go mind your own business!
find="string1|string2"
replace="string3"
insensitive="yes"
explode="|" — default: |
find="" accepts a pipe delimited list of strings to find and replace with the contents of replace="". Allows you to find all instances of a string and replace them with your desired text, or you can set replace="" to simply remove the matching string.
Optionally specify case sensitivity. Default is not case sensitive.
Optionally specify the explode parameter. Default is pipe.
You can also use Regex in your find="" parameter.
Example:
{exp:streeng find="well under way" replace="none of your concern"}
Our plans for world domination are well under way.
{/exp:streeng}
Result:
Our plans for world domination are none of your concern.
Example:
{exp:streeng find="http:\/\/(.*).com" replace="https://www.caddis.co"}
https://caddisint.com
{/exp:streeng}
Result:
https://www.caddis.co
Streng also provides some keywords to search for special characters.
find="NEWLINE" — Finds a new line
find="PIPE" — Find the | character
find="QUOTE — Find a prime quote: "
find="SPACE" — Find a space character
trim="left"
Specify the trimming of white space with this parameter. Default = "both"
encode="yes"
decode="yes"
specialchars="yes"
url="yes"
HTML encode or decode, or URL encode a string.
With encode="yes", a prime quotation mark would be encoded as " and ampersands encoded as &
When using encode you can also use encode_flags and encode_encoding parameters.
http://php.net/manual/en/function.html-entity-decode.php
When using decode you can also use decode_flags and decode_encoding parameters.
http://php.net/manual/en/function.htmlentities.php
When using specialchars you can also use specialchars_flags and specialchars_encoding parameters.
http://php.net/manual/en/function.htmlspecialchars.php
Example:
{exp:streeng encode="yes"}
"I'm a test" string & boy don't I look cool? Looking cool really helps with world domination!
{/exp:streeng}
Result:
"I'm a test" string & boy don't I look cool? Looking cool really helps with world domination!
This is really useful for protecting code examples and the like.
Example:
{exp:streeng encode="yes"}
Streeng will encode prime quotation marks as " entities.
{/exp:streeng}
Result:
Streeng will encode prime quotation marks as " entities.
Or you can reverse the process with decode="yes".
Example:
{exp:streeng decode="yes"}
Streeng will encode prime quotation marks as " entities.
{/exp:streeng}
Result:
Streeng will encode prime quotation marks as " entities.
If you need to url encode a string, use url="yes". Say you need to encode segments for use in a querystring. Like /account/login?return=my/url/segments. Of course those slashes in the querystring would need to be encoded.
Example:
{exp:streeng url="yes"}
my/url/segments
{/exp:streeng}
Result:
my%2Furl%2Fsegments
capitalize="yes" — capitalize the first character of the string
title="yes" — capitalize the first character of every word
lower="yes" — convert the string to lower case
upper="yes" – convert the string to upper case
All limiting and truncating will only count characters and words that are not HTML tags, and HTML tags will be auto-closed for you. In addition, character truncating is word aware and will not cut off words in the middle. Instead, Streeng will truncating immediately preceding the word that would otherwise be truncated.
Here are the parameters:
characters="20" — truncate the string by character count
words="10" — truncate the string by word count
append="&hellip" — if truncated this will be appended to the end of the string
This function will replace spaces in your string with dashes (default) or whatever you specify.
slug="yes" — Replace spaces in the string with dashes, or your specified separator
separator="_" — Optionally specify the separator to use in the slug
repeat="3" — Specify the number of times to repeat the string between the tag pair. This is in addition to the initial content. So if you specify the number 2, you will see your string three times.
count="|" — return the number of instances the supplied string appears. Pass "ALL" to count all characters.
splits="|" — return the number of exploded values from the supplied string
Use the typography parameter to parse a string through ExpressionEngine's typography parser. Valid options are:
allxhtmlbrlite
Example:
{exp:streeng typography="lite"}
"I'm a test" string & boy don't I look cool? Looking cool really helps with world domination!
{/exp:streeng}
Result:
“I’m a test” string & boy don’t I look cool? Looking cool really helps with world domination!
Example:
{exp:streeng typography="all"}
"I'm a test" string & boy don't I look cool? Looking cool really helps with world domination!
Paragraphs also are a good thing to have for world domination!
{/exp:streeng}
Result:
<p>“I’m a test” string & boy don’t I look cool? Looking cool really helps with world domination!</p>
<p>Paragraphs also are a good thing to have for world domination!</p>
